In signal processing, a comb filter is a filter implemented by adding a delayed version of a signal to itself, causing constructive and destructive interference.

Jul 10, 2022 · Comb filtering is a phenomenon that happens when the same sound arrives at the listener’s ears (or a microphone) at different times with a very small delay between the signals.

Comb Filters Comb filters are basic building blocks for digital audio effects. The acoustic echo simulation in Fig. 2.9 is one instance of a comb filter. This section presents the two basic comb …

What is comb filtering? comb filtering occurs when a sound adds to itself within a short time interval. Read our guide to learn more and avoid the problem.

Comb filtering occurs when two or more identical audio signals are mixed together with a slight delay between them. The resulting frequency response graph of these signals resembles a comb.
